我在Activity中有以下代码,它启动包含片段的布局的对话框。
...
case R.id.pick_resource:
dialog = new Dialog(this);
dialog.setContentView(R.layout.resource_picker);
dialog.setCancelable(true);
dialog.setTitle("Pick a resource");
dialog.show();
这在应用程序启动后第一次运行得非常好,但是当对话框退出并稍后再次调用时,我得到了这个堆栈跟踪:

任何想法,可能导致此异常的原因是什么?我必须以某种方式卸载片段吗?
答案 0 :(得分:27)
布局中的片段是否具有android:id属性?
我怀疑这是因为片段是在每次布局膨胀时实例化的,第一次没有使用ID,但第二次FragmentManager仍然认为你的片段还活着,所以ID被认为是重复的
尝试从片段中删除android:id属性(如果存在),或添加占位符布局(例如framelayout)并使用fragmenttransaction在每次创建对话框时动态添加片段。

我有类似的问题
我很容易解决它
关闭对话框时删除所有片段
这是我的对话
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="310dp"
android:layout_height="260dp" >
<fragment
android:layout_width="310dp"
android:layout_height="260dp"
android:tag="one"
class="com.android.mushrooms.CookingProgressFragment" />
<fragment
android:layout_width="310dp"
android:layout_height="260dp"
android:tag = "two"
class="com.android.mushrooms.CookingInfoFragment" />
</RelativeLayout>
这就是删除对话框时会发生的事情
dialog.findViewById(R.id.cifButtonClose)
.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
mDragController.endDrag();
FragmentTransaction ft2 = getSupportFragmentManager()
.beginTransaction();
ft2.remove( getSupportFragmentManager()
.findFragmentByTag("one"));
ft2.remove( getSupportFragmentManager()
.findFragmentByTag("two"));
ft2.commit();
dialog.dismiss();
}
});

尝试以下
public class ABDCD{
private Dialog dialog = null;
private View viewHoldingDialog = null;
----------------------------
case R.id.pick_resource:
dialog = new Dialog(this,R.style.Theme_Dialog_Translucent);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
viewHoldingDialog = (ViewGroup) layoutInflater.inflate(
R.layout.resource_picker, null);
dialogLayoutParams = new LayoutParams(android.view.WindowManager.LayoutParams.WRAP_CONTENT, android.view.WindowManager.LayoutParams.WRAP_CONTENT);
dialog.addContentView(viewHoldingDialog,
dialogLayoutParams);
}
答案 3 :(得分:1)
也许这可以帮助某人:
我使用ЭвансгелистEvansgelist的代码,但是使用具有MapFragment布局的DialogFragment,代码必须是onDestroy块:
@Override
public void onDestroy(){
super.onDestroy();
FragmentTransaction ft2 = getActivity().getFragmentManager()
.beginTransaction();
ft2.remove( getFragmentManager()
.findFragmentById(R.id.map_map));
ft2.commit();
}
这是我的布局:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example"
>
<fragment
android:id="@+id/map_map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
</FrameLayout>
答案 4 :(得分:1)
On android.view.inflateexception: binary xml file line #8: error inflating class fragment error :
尝试从片段中删除android:id属性(如果存在)。 并在关闭对话框中添加以下代码:它适用于我
activity.getFragmentManager().beginTransaction().remove(activity.getFragmentManager().findFragmentById(R.id.mMap_location)).commit();
答案 5 :(得分:0)
另一个可以帮助其他人的答案:我遇到了类似的问题但是我没有破坏onDestroy中的片段,而是将其移动到onPause以使其工作:
@Override
protected void onPause() {
if(adFragment != null){
childFragmentManager.beginTransaction().remove(adFragment).commitAllowingStateLoss();
}
super.onPause();
}
